Slim Cavity Units for St Helens properties
Most Slim Cavity Units enquiries we take in St Helens start with an opening that is not a standard size. Local property is overwhelmingly Georgian merchant housing, dockland terraces and Victorian resort villas, which is why we never quote from a catalogue. With Irish Sea exposure with salt-laden prevailing wind in the mix, salt-accelerated finish breakdown on west-facing elevations is a question of when rather than whether. The part that matters is narrow cavities that perform while keeping the sightline historic.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. One call is usually enough for us to tell you roughly where the price will land.
Something particular to this area: Liverpool's Georgian quarter carries strict conservation-area window controls.
